20 September,2005: The British health authorities warned the consumers some traditional Chinese medicines (TCM) in the UK market could pose health risks.
Alerting the herbal sector about the poor quality of some traditional herbal medicines, the Medicines and Healthcare products Regulatory Agency (MHRA) of UK has recently identified a number of TCMs which contain ingredients that could pose a risk to consumers' health.
The regulatory watch-dog reminded consumers through an official release that they cannot give assurances about the quality of these unlicensed traditional herbal medicines and remedies and to give an update on action to address the problem.
Under current regulations, unlicensed herbal medicines, from China or anywhere else, do not have to meet set standards of quality and safety. However, if these herbal products are found containing illegal or potent ingredients, such as prescription-only medicines, the MHRA can remove them from sale, said the release.
Examples of incidents Chinese herbals currently being investigated by MHRA include:
- The Chinese dietary supplement, Shubao; samples of this herbal dietary supplement have been found to contain fenfluramine (banned worldwide after being linked with cardiac problems) and/or nitrosfenfluramine (toxic to the liver); -
Fufang luhui jiaonang, supplied by a Traditional Chinese herbal medicine outlet was investigated by the agency and found to contain high levels of mercury - 11.7% by weight. The product was recalled from 35 TCM outlets.
Other ingredients found to be illegally included in Traditional Chinese herbal medicines in recent months have included the banned ingredient Aristolochia, associated with kidney failure and cancer; prescription-only ingredients glibenclamide (used in the treatment of diabetes; improper use can be fatal) and corticosteroids (found in 'herbal' skin creams). The TCMs involved have been in a number of forms, including pills and capsules.
Sir Alasdair Breckenridge, chair of the MHRA, said: "Our advice to consumers is not to take TCMs if they are not labelled in English. Even then you should be aware that good labelling is not a guarantee of a good quality product. If you are taking one of the specific traditional chinese medicines identified as posing a risk, stop taking it and consult your GP if you feel unwell. When consulting your doctor or pharmacist about your health, always remember to tell them if you are taking TCMs or other herbal remedies."
The European Directive on Traditional Herbal Medicinal Products will set out clear standards for the safety and quality of over the counter traditional herbal medicines and is due to be implemented in 2005.
